Fog bow is an atmospheric phenomena similar to rainbow, but because of the very small size of water droplets that cause fog, the fog bow usually has no colors and appears white (they are sometimes called white rainbows), as photographed in this night-time photograph from Cape Spear, the eastern most point of the North America in the Newfoundland province of Canada. As noted by the photographer "The source of light in this photo is in fact a high powered security light at a nearby parking lot!" Yuichi Takasaka/Blue-moon.ca
